OBJECTIVE To analyze endometrial mRNA and protein expression of osteopontin and its receptor, beta3-integrin, throughout the menstrual cycle. DESIGN Study by immunohistochemistry, RNase protection assay, and ELISA. SETTING Academic research unit. PATIENT(S) Forty-five regularly cycling women without endometrial pathology. INTERVENTION(S) Expression(More)
The sarcoglycan-sarcospan complex (alpha-, beta-, gamma-, delta-, epsilon-, and zeta-SG-SSPN), a component of the dystrophin-associated glycoprotein complex (DAGC), is located at the sarcolemma of muscle fibers where it contributes to maintain cell integrity during contraction-relaxation cycles; gamma- and delta-SG are also expressed in the sarcoplasmic(More)
Experiments were performed to determine whether the organic Ca(2+) channel blocker D-600 (gallopamil), which penetrates into muscle cells, affects sarcoplasmic reticulum (SR) Ca(2+) uptake by directly inhibiting the light SR Ca(2+)-ATPase. We have previously shown that at 10 microM, D-600 inhibits LSR ATP-dependent Ca(2+) uptake by 50% but has no effect on(More)
The sarcoplasmic reticulum (SR) Ca(2+) pump is the main homeostatic regulatory mechanism in fast skeletal muscle that maintains intracellular Ca(2+) concentration ([Ca(2+)](i)) at the nanomolar level at rest. The transverse tubule (TT) Ca(2+) pump transports cytosolic Ca(2+) to the extracellular space. During prolonged muscular activity, [Ca(2+)](i) may(More)

Previous findings revealing reduced endometrial interleukin-6 (IL-6) mRNA expression in patients with recurrent early abortions gave rise to the analysis of IL-6 synthesis in the human endometrium, and how it relates to concentrations in uterine secretions. Endometrial tissues and uterine secretions were collected from patients undergoing hysterectomy.(More)
Sixty-two uremic patients on dialysis of varying durations were tested bilaterally for posterior tibial nerve H-reflex latency, at 3-month intervals. Bilateral nerve conduction velocities (NCVs) of the peroneal, tibial, and sural nerves were concomitantly determined in all subjects. Proprioception sense, vibration perception threshold at the great toes, and(More)
